binutils 2.9 powerpc-rtems breakage

[Joel Sherrill <joel@OARcorp.com>]

I switched binutils 2.9 in my tree for gas-980314 and was unable to
complete a one-tree style build of binutils 2.9, egcs 1.0.2, and newlib
1.8.0.  The compilation aborted when trying to compile libgcc2.c for
_muldi3.  I cut the command down to the following:

/usr1/rtems/work/tools/build-powerpc-tools/gcc/xgcc \
  -B/usr1/rtems/work/tools/build-powerpc-tools/gcc/ -O2  -DCROSS_COMPILE \
  -DIN_GCC    -O2 -I./include   -g1 -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED \
  -fexceptions -Dinhibit_libc   -mlittle -mrelocatable-lib -mno-eabi \
  -mstrict-align -I. -I../../src/gcc -I../../src/gcc/config -DL_muldi3 \
      ../../src/gcc/libgcc2.c -c -v

which produces the following output:

I can produce a .s file using -s and then assemble that file with:

./as -mppc -V -Qy -mrelocatable-lib libgcc2.s

which indicates to me that somehow the rtems configuration lost support
for the -mlittle option.  powerpc-rtems should be identical to
powerpc-eabi if that trips anyone's memory.

Thanks.
